Against the Academics

Against the Academics (Contra academicos, 386) was
Augustine of Hippo's first writing after his conversion to Christianity. It is a polemic against the value of academic skepticism as found in Cicero's philosophical dialogue Academica. A similar refutation
to skepticism can be found in his more mature On the Trinity (De trinitate, 400-416). Academic skepticism was the product of two centuries of debate within Greek Hellenistic thought, ending just after the time of Cicero (died 43 BC).
